TROLLEY-WEEEIJ MOUNT.

To rzllwlmm it may concern: I i

Be it known that I, THOMAS SANDE S, a citizen of the United; States,residing, at Kingman, inthe county of Fountain, Indiana, have inventedanew anduseful Improvement in Trolley-lVheel Mounts, of which thefollowing is a specification. 7

My invention relates to that class of trolley-wheel mounts, wherein asubstantial mount is provided whereby a trolley-wheel is supportedinbearings, and upon the extreme end of a trolley-pole, and the objectsof the invention are: first, to providea suitable bearing and supportfor a trolley-wheel upon the extreme end of atrolley-pole; sec- 0nd, toprovide such a trolley-wheel mount. which by reason of its pecularstructure and attachments, permits an automatic adjustment in theposition of the trolley-wheel while traversing a curve, for the purposeof avoiding the danger of the trolley-wheel jumping the wire; and thirdto provide such a trolley-wheel mount, which will be substantial,sightly and safe against dis placement; These objects I attain bymeansof the mechanism illustrated in the accompanying drawings, in whichFigure 1, is a side viewof the trolleywheel and mount. Fig. 2, is avertical sectional view of the mount. Fig. 3, is a front view of thetrolley-wheel and its mount.

Similar letters of reference refer to simi-' lar parts throughout theseveral views.

The letter a indicates a trolley-wheel, of the usual shive-wheel type,provided with a hollow hub 12, supported rotatably upon a shaft 0. Thehub b is perforated to form an oil-vent (Z, said oil-vent extending fromthe outer side of the hub in a diagonal direction downward toward thecenter of the shaft 0, and for the purpose of lubricating the saidshaft.

The letter A indicates a trolley-wheel mount, which consists of atrolley-head 6 and a head-stock f.

The trolley-head e consists of a U-shaped, I

or fork-like muinbenflcomposed of a solid base 9 and two parallel,upwardly project ing bearihg-arms'lt.

The bearingarms )h are perforated at their upper ends, said perforationsbeing disposed opposite one to the other, and form ing journal-bearings6, wherein the extreme ends of the shaft 0 are journaled, respectively.

The base 9 of the trolley-tread is'perfo- Specification (if LettersPatent.

rated vertically and centrally to admit the hereinafter describedjournal-pin 9', upon which the trolley rotates. The extreme ends of theshaft 0 are journaled in the journalbearings 71 and said shaft supportsthe trol'-' ley-wheel a. The extreme ends of the shaft 0 project beyondthe journal-bearings i, and are perforated to receive the .cotter-pinsm,respectively, whereby said shaft is prevented from lateral movement. Thetrolley-head is flat upon either side, for the purpose of presenting aflat bearing surface to two retain-e ing springs s, hereinafterdescribed.

The head stock f consists of'a metallic, cone-shaped member, flattenedupon two opposite sides, and inverted to place the larger end upward.The central portion of the head-stock f is perforated horizontally by alarge slot t, for the purpose of reducing the weightof the stock, and topermit the placement of the journal-pin j. The upper portion of thestock f'is provided with a perthreaded perforation n, adapted to receivethe ournal-pin j, as-shown. The journalpm 9' is provided'with externalthreads'u, throughout its lower portion, adapted to screw into thethreaded perforation n of the head-stock f; and the upper portionisproportioned .to nicely fit into the vertical erforat'ionvprovidedtherefor in the base 0 l the "trolley-head e.

The journal-pin j is provided with a head 0 upon the lower end, adaptedto seatitself firmly against the body of the stock, and is perforated atthe upper and projecting end. to receive a cotter-pin 9, whereby thetrqlley-head is'confined upon said journal-pin! The lower portion of thehead-stock f is hollow perpendicularly, and adapted to receive the outerend of a trolley-pole w, upon which the trolley-mount is supported and.firmly attached by means'of a pin 0, which passes through opposite sidesof the lower end of the head-stock and the trolley-pole, respectively. Abroad, flat spring 8, wide at the upper end and tapering toward thebttom, is firmly attached by means of screws 9 to either flattened sideof the head-stock, and is so positioned that the broad, u per endthereof, will project upward and ear against the flattened sides of thetrolleyhead, respectively, as shown. The springs .9 are disposedopposite to each other, and are so adjusted that they bear firmlyagainstthe corresponding: sides I of the trolley-head,

thereby serving to hold the trolley-head and its wheels in perfectalinement with the head-stock, and incidentally in perfect alinementwith a straight trolley-wire as, against which the trolley-pole holdssaid wheel.

The springs s are designed with proper nicely proportioned pressureexerted by the springs s, the trolley-wheel is at all times held inperfect alinement with the trolleywire it follows, and all dangerisavoided of said wheel crossing or jumping the wire, and. causing brokencross-wire and 5 V a rotatable trolley-head, and a fixed headothertroubles incidentto such accidents,

The advantages claimed for my inven' tion, over similar devices usedheretofore, consist 'in the simple, compact, and substantial structureof the mount; the nicely adjusted flexibility of the trolley-head,attained by reason of the peculiar structure thereof. t

What I claim as new and useful, and desire to secure by Letters Patent,is:

1. The combination with a rotatable trolley-head and trolley-wheel axleor shaft, with a head-stock, adapted to movably support saidtrolley-head, a journal-pin fixed centrally on the body of saidhead-stock and adapted to confine said trolley-head in movableconnection with said head-stock, a pair of oppositely disposed springsattached to said head-stock, and adapted to bear upon opposite sides ofsaid trolley-head, all substantially as described and for the purposeset forth.

mounted upon opposite sides of said headareas re 2'. In a'trolley-wheelmount, the combination of a rotatable trolley-head, said trolleyheadconsisting of a base and two bearingarms; and journal-bearing in saidbearingarlns, adapted to receive a trolley-wheel axle, or shaft, withahead-stock adaptedto support said trolley-head upon its upper face, ajournal-pin threaded centrally into and projecting upwardly fromtheupper face of said headstock, and adapted to confine said trolley-headin movable" connection with the head-stock, two opposing springs,

stock and projecting upwardly, and adapted to press against oppositesides of said trolley-head, and means of attaching saidheadstock uponthe extreme end of a' trolley-pole, all substantially "as described andshown,

and for the purposes set forth.

3. Ina trolley-wheel mount,- consisting of stock, in movable connectionwith each other, means of attaching-said members together, a pair ofopposing springs, fixed upon the respective sides of said head-stock andadapted 'to bear against the corresponding sides ofsaid trolley-head, ahollow, lower portion of said head-stock adapted to receive the end of atrolley-pole, means of attaching said head stock to a trolley-pole, anda trolley-wheel shaft journaled in, and supported by, said trolley-head,all substantially as described and shown, and for the pur poses setforth,

In testimony that I claim the foregoing as my own, I have affixed 'mysignature hereto, in the presence of two Witnesses.
